Javaris Crittenton arrested near Atlanta

Former NBA [player] Javaris Crittenton was arrested outside Atlanta this morning — after he allegedly shattered the speed limit in his black Porsche … then refused to cooperate with police.

Law enforcement sources tell TMZ, Javaris was pulled over for going over 60 in a 45 — and when the cop wrote up the ticket … Javaris refused to sign it, something you have to do to acknowledge receipt of the citation.

As a result, we’re told the officer asked Javaris to step out of the vehicle — and Javaris refused again.
